Cumulative Frequency Table (Grouped data)
The following table gives the frequency distribution of mass of 40 objects.
Mass (g) 10–14 15–19 20–24 25–29 30–34 35–39 40–44
Frequency 3 4 10 12 6 3 2
Construct a cumulative frequency table for the given data.
Solution:
Mass Upper class boundaries Frequency Mass less than Cumulative Frequency
10 – 14 14.5 3 14.5 3
15 – 19 19.5 4 19.5 3 + 4 = 7
20 – 24 24.5 10 24.5 7 + 10 = 17
25 – 29 29.5 12 29.5 17 + 12 = 29
30 – 34 34.5 6 34.5 29 + 6 = 35
35 – 39 39.5 3 39.5 35 + 3 = 38
40 – 44 44.5 2 44.5 38 + 2 = 40
